This cat lives in the apartment building next to mine and she peers out the window at the world close to 24 hours a day. Which isn't all that un-cat-like save for the fact that she has two other kitty siblings that live with her. It is rarest of rare that I ever see them in any of the windows, but when I do, they are sandwiched on either side of her in the bedroom window. Yes, neighbors...I pay way too much attention, but I swear I'm no peeping Tom(asina).
I think kitty's mum leaves the chair you see behind her close enough to the window for her to jump on the sill. What a sweet lady!
